How should I manage deployments with kubernetes -


i hoping find way automate process of going code deployed application on kubernetes cluster.

in order build , deploy app need first build docker image, tag it, , push ecr. need update deployment.yaml new tag docker image , run deployment kubectl apply -f deployment.yaml.

this go , perform rolling deployment on kubernetes cluster updating pods new version of container image, once deployment has completed may need other application specific things such running database migrations, or cache clear/warming may or may not need run given deployment.

i suppose write shell script runs of these commands, , run whenever want start new deployment, hoping there better/industry standard way solve these problems have missed.

as writing question noticed stackoverflow recommend question: kubernetes deployments. 1 of answers seems imply @ least of looking coming kubernetes, want make sure if there better solution using @ least know it.

my colleague has blog post topic:

http://blog.jonparrott.com/building-a-paas-on-kubernetes/

basically, kubernetes not platform-as-a-service, it's toolkit on can build own platform-a-as-service. it's not opinionated design, instead focuses on solving tricky problems scheduling, networking, , coordinating containers, , lets layer in opinions on top of it.

one of simplest ways automate workflows you're describing using makefile.

a step that, can design own miniature paas, author of first blog post did here:

https://github.com/jonparrott/noel

or, involved in more sophisticated efforts build open source paas on kubernetes, openshift:

https://www.openshift.com/

or deis, building heroku-like platform on kubernetes:

https://deis.com/

or redspread, building "git kubernetes cluster":

https://redspread.com/

and there many other examples of people building paas on top of kubernetes. think long time, if ever, there "industry standard" way deploy kubernetes, since half purpose enable multiple deployment workflows different use cases.

i want note far building container images, google cloud container builder can useful tool, since can things use automatically build image time push repository deployed. alternatively, jenkins popular way automate ci/cd flows kubernetes.

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
